 Roots in the soil are a very, very complex system, so the fine roots are not visible. If you pull out a plant, you only see the more coarse roots. The fine ones are only visible under a microscope and they will die off every two, three days leaving new roots are built. The roots can be enormously extended and supported by specific fungi that are called mycorrhiza. It's natural, so if you have a very healthy, good forest soil, mycorrhiza is there. If you have an agricultural land, if there is an agrochemical agriculture going on since some time, no mycorrhiza, plowing destroys them, pesticides destroy them, mineral fertilizer destroys them. So one of our most beneficial support systems, the mycorrhiza fungi, is normally destroyed. So in reproductive agriculture and of course in organic agriculture, a lot of this is done in organic agriculture, but now the conventional goes this way, so I'm lucky that we have that. And the mycorrhiza fungi make a network here, a very fine network and the root of the tree may go here. But the mycorrhiza can go here and it actually can go to another tree here, connect them. They can send nutrients from this to this, they can send information from here to there. If there is an animal grazing this tree, this tree can send a signal through the mycorrhiza fungi, take care, bring out your bitter stuff that you don't taste well anymore so that you are not grazed down. And this is an amazing network and one of the big benefits is that the phosphate can be activated in a very, very wide range, also deep down. And phosphate is often considered one of the big limitations in agriculture. If you have mycorrhiza fungi, you can access phosphate that would be never accessible otherwise. So once again, you don't have to buy this because a lot of land has phosphate for hundreds of years. I heard numbers that many soils hold phosphate for 500 years minimum. And so if there is mycorrhiza fungi, you have access to an enormous wealth of your soil that you haven't been aware of. Instead of buying this, just access this with your little helpers and only thing you have to do is provide them a living environment where they can thrive.
